Description

The AA210-25 is an IC FET digital attenuator consisting of four

monolithic attenuators with LSB of 1 dB and a total attenuation

of 15 dB with all attenuators connected. Attenuator bits are

switched with -5 and 0 V. The AA210-25 is particularly suited

where high attenuation accuracy, low insertion loss, and low

intermodulation products are required. Typical applications

include cellular, radio, wireless data, wireless local loop, and

other gain/level control circuits.

Performance is guaranteed only under the conditions listed in the specifications table and is

not guaranteed under the full range(s) described by the Absolute Maximum specifications.

Exceeding any of the absolute maximum/minimum specifications may result in permanent

damage to the device and will void the warranty.

CAUTION: Although this device is designed to be as robust as

possible, ESD (Electrostatic Discharge) can damage

this device. This device must be protected at all times

from ESD. Static charges may easily produce poten-

tials of several kilovolts on the human body or

equipment, which can discharge without detection.

Industry-standard ESD precautions must be employed

at all times.
